Location: Ladue, MO
Job Type: Foundation Piering
A new Squash court addition was being added to this residence. The lower elevation of the squash court was approximately 15 ft. below the existing footing elevation of the residence.
As a result of the excavation involved to construct the addition and the code clearance requirements involved, Helitech constructed a temporary shotcrete wall to retain the vertical cut for this St. Louis County home. Sheet piling was not an option, due to the impact it would have induced upon the residence, and the timber/lag retention system was not an economical solution.
Helitech installed (10) ten A.B. Chance Helical Piers to support the North & West foundation walls. Helitech then transferred loads of the structure to the piers, which reduced surcharge loading of the soil. Piers were installed to 30-50 Kip capacities and consisted of an 8-10-12 in. diameter helix configuration. Piers reached load capacities at 20-30 ft. depths.

Had Helitech come out to our home in Belleville and they were professional when explaining the issue and provided us with a solution. We moved forward with the project and glad we did…no more water in our basement!
